AI trip planner input guide

12 details that make an AI itinerary more useful

A better itinerary starts with the real shape of the trip—not a longer prompt full of tourist attractions.

Veroo editorial team

The short answer

Tell an AI trip planner the destination or options, dates, arrival and departure, travelers, pace, budget, interests, must-keep experiences, practical constraints, existing bookings, open questions, and which choices are already confirmed. You do not need all 12 before starting. Add missing details later, and keep suggestions separate from decisions you have actually made.

Before you build the itinerary

Four rules make the rest of the plan easier

Use these as decision rules rather than trying to predict every detail before the family starts talking.

Start incomplete

A destination idea and a few constraints are enough to begin. Add details when the family learns or decides more.

Describe the travelers

A useful plan reflects who is going, their interests, pace, mobility, food needs, and tolerance for transfers.

Separate facts from preferences

Booked flights and dates constrain the plan differently from a neighborhood someone is merely considering.

Label the decision status

Say when you want a comparison, when an option is still open, and when a decision should update the itinerary.

A natural-language example

You can say it like this—without filling in a form

This example includes the details that matter, but it still sounds like a normal conversation. Shorten it to whatever you know today and continue later.

We are planning eight days in Italy in November for four adults, including my parents. Rome and Florence are fixed because the flights and hotels are booked. We want one main experience per day, a 9:30 start, seated lunches, and an afternoon hotel rest. My mom needs shorter level walks and fewer queues; my dad cares most about Roman history, Renaissance art, and wine. We have about $6,500 after flights and hotels. The Colosseum and St. Peter’s matter, but a full Vatican Museums route is optional. We are still comparing Tuscany with another slow Florence day. Please show the tradeoffs, but do not choose or write an option into the itinerary until we confirm it.

1. Define the basic shape of the trip

These four details establish the frame. If one is unknown, say that it is still open instead of inventing precision.

1. Destination or candidate destinations

Name the place you chose or the small set you are comparing. Make it clear when the destination itself is not decided.

2. Dates and total length

Share fixed dates, a flexible window, and how many nights or full days the trip can actually use.

3. Arrival and departure

Include times, airports or stations, and transport already booked so the first and last days are not treated as full sightseeing days.

4. Travelers and age groups

Explain who is going together and any age, mobility, sleep, or supervision needs that affect the group’s pace.

2. Describe the experience the group can sustain

An itinerary becomes useful when the AI understands what a good day feels like and what would make it fail.

5. Travel pace

Say how early the group starts, how many main commitments fit, and whether rest or unscheduled time is part of a successful day.

6. Budget and spending priorities

Give a useful range and name where comfort is worth paying for, such as taxis, a private driver, or one special meal.

7. Interests and explicit dislikes

Include what each traveler values and what the group does not want, such as checklist travel, nightlife, long shopping stops, or crowded tours.

8. Practical constraints

Describe food needs, walking, stairs, standing, transfers, climate tolerance, children’s schedules, or any other condition that changes the route.

3. Make commitments and decision status explicit

This is what prevents an attractive suggestion from quietly becoming the current itinerary.

9. Must-keep experiences

Name the sights, meals, visits, or family moments that should survive later itinerary adjustments whenever possible.

10. Existing bookings

Record flights, hotels, trains, timed tickets, deposits, and cancellation conditions as confirmed facts with dates and times.

11. Open questions

List choices that still need comparison, family agreement, price checks, or confirmation from an official provider.

12. Suggested versus confirmed

Tell the AI whether to brainstorm, compare, propose a revision, or apply a decision to the current itinerary.

Useful phrases include: “compare these but do not choose,” “propose the changes first,” “we confirmed this option,” and “answer without updating the itinerary.”

4. Add new details without restarting the conversation

A real trip develops over time. New facts should refine the same plan instead of forcing another one-shot prompt.

Correct outdated information

Say which earlier date, budget, route, or limit is no longer current so the plan does not retain two conflicting facts.

Ask for impact before changing

When a new constraint appears, ask which days and commitments it affects before accepting a revised itinerary.

Confirm the chosen option

After reviewing a comparison, state the decision clearly and identify any details that should remain open.

Ask questions without saving

A route explanation or tradeoff question does not need to alter the itinerary when it adds no confirmed trip fact.

From a real Veroo recording

Three inputs, three different jobs

Turn 1 establishes the trip from a long, messy family brief. Turn 3 requests a comparison and explicitly prevents either option from becoming a decision. Turn 7 asks for an explanation and explicitly leaves the State unchanged. Every card reads the original recording fields.

Initialized the November 2026 Italy trip with confirmed bookings, family needs, budget, and open sightseeing choices.

My partner and I are taking my parents to Italy from November 18 to 25, 2026. It will be their first real trip to Europe. The flights and hotels are already booked: we land at Fiumicino at 10:45 a.m. on the 18th, stay four nights near Monti in Rome, take the train to Florence on the 22nd, stay three nights near Santa Maria Novella, and fly home from Florence at 1:20 p.m. on the 25th. We do not want to change hotels again. My dad cares most about Roman history, Renaissance art, and wine. My mom wants beautiful streets, a market or two, and time to browse small shops, but her knee has been unreliable. On our last family trip we packed in too much, rushed every morning, and everyone was exhausted by dinner, so this time we would rather miss a famous sight than turn each day into a checklist. Excluding flights and hotels, we have about $6,500 for food, tickets, local transportation, and one special dinner. We have mentioned the Colosseum, the Vatican, the Pantheon, the Uffizi, seeing the Duomo, and possibly one day outside Florence, but the family group chat is all over the place. We need a calm overall plan that still feels worth the trip.

Updated the final Florence-day choice to compare Tuscany and Bologna without selecting either option.

The main disagreement now is the day outside Florence. My dad likes the idea of a Tuscany day with a winery and an old town, but I am worried that the usual Siena and San Gimignano group tours are ten or eleven hours, involve hills and uneven streets, and give us no control over rest. My mom is more interested in Bologna because of the covered porticoes, food, and direct train, although adding another city may make the trip feel fragmented. None of us needs to collect destinations just to say we went. Please compare a Tuscany day and a Bologna day based on travel time, walking and terrain, crowding, my parents’ interests, how much control we would have over breaks, and the effect on the other Florence days. Help us judge the tradeoff, but do not choose for us and do not write either option as decided.

Answer only

The question was answered without changing the saved State.

I understand the revised plan, but I want to know why you kept the Pantheon and Piazza Navona area on November 21 instead of combining it with the Colosseum on November 19. They look fairly close on a map, but I cannot tell whether the entrances, standing time, pavement, taxi drop-offs, and the hotel rest would make the combined day harder for my mom under the 5,000-step limit. Please explain your reasoning using the route, expected walking, the days around it, and the November 20 dinner commitment. We have not decided to change anything, so answer the question without updating the State.

Questions about planning with older parents

Do I need a perfect AI trip planner prompt?

No. Start with the destination idea, travelers, dates, and the constraints you already know. Add missing details and corrections as the trip develops.

What information matters most at the beginning?

Start with fixed dates and bookings, who is traveling, the desired pace, practical constraints, and the important decisions that are still open.

Should I list every attraction I might visit?

No. A short list of must-keep experiences and interests is more useful than a large attraction dump. Leave room to compare what fits the real pace.

How do I stop an AI from treating a suggestion as decided?

Use explicit decision language: ask it to compare without choosing, propose changes before applying them, and update the itinerary only after you confirm the option.

Can I ask a question without changing the trip plan?

Yes. Say that you only want an explanation and have not decided to change anything. In Veroo, an answer can remain in the conversation without creating a State update.

Start with the trip details you already know.

You do not need to turn your family conversation into a perfect prompt. Say what is fixed, what matters, and what is still open.
